Abstract
Method is claimed for protection of mine workings against underground waters. To increase reliability of water insulation of workings through provision of stability of anti-filtration screen under conditions of increased inflow of highly mineralized underground waters and cyclic change of temperature of rock massif from (-) to (+) as solution pumped in to wells one uses clay-silicate mix at following component ratio, mass %: clay 30-50, sodium silicate 8-14, water the rest.
